I suggest using a flat-file CMS, which is easy to deploy and suited for your case. There are plenty, but I did really enjoy Automad.
If you still want something more sophisticated, I can recommend Contao CMS, which has lots of solid core features, is extendable and easy to install via their «Contao Manager».

I find GeoGebra a handy solution.
